4.Effects of photodynamic therapy on microvessels and vascular endothelial growth factor expression in transplanted mouse Heps liver carcinoma
Journal of Medical Postgraduates 2003;0(04):-
Objective: Hitherto there has been no report on the changes of microvessels and the expression of angiogenic factors after photodynamic therapy(PDT) of liver carcinoma.The purpose of this study was to investigate the effect of PDT on the microvessels and the expression of vascular endothelial growth factors(VEGF) in tumor cells. Methods: The mice models subcutaneously transplanted with Heps liver carcinoma were randomly divided into a PDT group(n= 28) and a control group(n= 28).The dynamic changes of the microvessels and VEGF expression in the tumor cells were observed at 2,6,24 and 72 h after PDT by H-E and immunohistochemical staining.Results: Progressive changes were seen in the tumor microvessels at the four time points after PDT,including dilatation,blood stasis,hypostasis,hemorrhage,and angiolysis.Compared with the control group,the microvessel density of the tumors was reduced significantly(P
5.Amnioreduction in management of twin-twin transfusion syndrome
Chinese Journal of Perinatal Medicine 2009;12(3):194-196
Objective To find out the clinical outcomes of twin-twin transfusion syndrome (TTTS) after aminioreduction. Methods Twenty-nine pregnancies with TTTS delivered in Beijing Gynecological and Obstetric Hospital from Nov. 1, 2002 to Sept. 30, 2007 were recruited. The effect of gestational age at the onset, the degree of TTTS and amnioreduction therapy on the fetal outcomes were compared. Results All of the 8 cases with the onset of TTTS before 26 weeks without treat- ment were lost, but 4 out of the 6 with the onset after 26 weeks survived (P=0. 015). Among the 9 cases received amnioreduction, 4 out of the 5 with onset before 26 weeks survived, and significant difference was found compared to those untreated ones (P= 0. 007), but no difference was shown when compared with those developed after 26 weeks(4/4)(P= 1. 000). The average delivery weeks in the untreated ones was earlier than those received treatment E(28.7±4.7)weeks vs (33.2±4.9) weeks, P=0. 001]. Amnioreduction improved the umbilical cord blood flow. For severe TTTS(stage Ⅲ~Ⅳ) with the onset before 26 weeks, the survival rate after amnioreduction was significantly high- er than those untreated ones[4/5 vs 0/5, P=0. 048)]. Conclusions Aminioreduetion is effective in improving the cord blood flow, prolonging the pregnancies, and achieving a higher fetal survival rate.
7.Autologous mesenchymal stem cell transplantation induces angiogenesis in rat ischemic limbs Significance of monocyte chemoattractant protein-1 changes in plasma and ischemic tissues
Chinese Journal of Tissue Engineering Research 2009;13(49):9771-9774
OBJECTIVE: To observe monocyte chemoattractant protein 1 (MCP-1) changes in ischemic tissue during the process of angiogenesis induction in ischemic limbs by autologous mesenchymal stem cell (MSC) transplantation.METHODS: Twenty male Sprague-Dawley rats were randomized to 2 groups (n = 10): model and MSC transplantation. Femoral and tibial bone marrow was taken to isolate and culture MSCs by percoll density gradient method. Cells of the 3~(rd) or 4~(th) passage were used for transplantation. Severe bilateral hind limb ischemia was surgically created in each group rats. Two hours after model establishment, MSCs (1×10~(11)/L) were infused into the ischemic region of rats from the MSC transplantation group, and the model group received the same amount of phosphate buffered saline. Collateral artery formation was determined by angiographic analysis and histological assessment. CD68~+ macrophage infiltration was examined by immunohistochemistry. MCP-1 protein expression in the plasma and ischemic tissue was detected by enzyme-linked immunosorbent assay. MCP-1 mRNA expression in ischemic tissue was detected by reverse transcription-polymerase chain reaction.RESULTS: At postoperative 28 days, treatment with MSC transplantation lead to collateral vessel formation, and immunohistochemistry demonstrated that CD68~+ macrophage infiltration was lower compared with the model group. MCP-1 protein and mRNA expression in the plasma and ischemia tissue was significantly lower in the MSC transplantation group than in the model group (P < 0.05).CONCLUSION: Following MSC transplantation, MCP-1 may play an important role in ischemia-induced angiogenesis. This indicates that MCP-1 would become one possible target molecule for modulating inflammatory angiogenesis by MSC Transplantation.

10.The preliminary study of the effect of ritodrine on the change of heart rate in threatened premature labor.
Chinese Journal of Practical Gynecology and Obstetrics 2001;17(4):228-230
Objective To determine the change of maternal heart rate during the treatment with ritodrine for threatened premature labor. Methods110 cases of threatened premature labor were chosen. The ritodrine 100mg in 5% G. S 500mL was intravenously administered. The initial dosage was 6 drops/min, and the dose was increased until uterine contractions were inhibited. The treatment lasted for 40 to 48 hours after the uterine contractions were inhibited, then the oral tablets was recommended. If necessary, repeated treatment was given to some patients. The maternal heart rate was recorded in the whole process of treatment and was compared with the dosage administered. The labor time, fetal weight and Apgar′s score were also analyzed. Results The maternal basic heart rate was increased at first and then decreased. The increasing significantly increased( P < 0.01 ) when the uterine contraction was inhibited. , but no difference showed among the groups of different gestational age( P>0.05 ). The maternal heart rate was increased with the increasing of ritodrine( max. 140/min). labor time was significantly prolonged with the treatment of ritodrine( P<0.01 ) ,while that of the idiopathic premature labor was prolonged most obviously ( P < 0.05 ). Average fetal weight was (2.42 ± 0.49) kg, and the average Apgar′s score was≥8. Conclusion In the treatment of inhibiting uterine contractions,the increasing of maternal heart rate caused by ritodrine can be used as an indicator of therapeutic effect.
